2 Axes Linear Interpolation Control

Linear interpolation control from the current stop position with the specified 2 axes is executed.
ABS-2 (Absolute data method) and INC-2 (Incremental data method) servo instructions are used in the 2 axes linear
interpolation control.

Processing details
■Control using ABS-2 (Absolute data method)
• 2 axes linear interpolation from the current stop address (X
or Y ) is executed.

• The travel direction is set by the stop address (starting address) and positioning address of each axis.
